A quantitative measure of the extent to which a compound absorbs radiation of a particular wavelength. A 5 log (I0/I ) where I0 is the incident radiation and I is the transmitted radiation
An object that lacks chirality; an object that has no handedness
An SR group.
alpha (a) amino acid
A compound containing a carboxylic acid group (COOH) as well as an amino group (NH2), both of which are attached to the same carbon atom.

beta (b) pleated sheet
For proteins, a feature of secondary structure that forms when two or more protein chains line up side-by-side.
An atom or group of atoms bearing a positive charge.
The process by which a metal is oxidized by substances in its environment. (Section 20.8)
Any substituent on a benzene ring that causes the rate of electrophilic aromatic substitution to be lower than that for benzene.
A graph showing the changes in energy that occur during a chemical reaction; energy is plotted on the vertical axis, and reaction progress is plotted on the horizontal axis. Also called a reaction coordinate diagram
frontier orbital theory
The analysis of a reaction using MO theory, where only the frontier orbitals (HOMO and LUMO) are considered.
A characteristic group of atoms/bonds that possess a predictable chemical behavior.
A polyhydroxy aldehyde whose formula is CH2OH1CHOH24CHO; it is the most important of the monosaccharides. (Section 24.8)
nematic liquid crystalline phase
A liquid crystal in which the molecules are aligned in the same general direction, along their long axes, but in which the ends of the molecules are not aligned. (Section 11.7)
nuclear disintegration series
A series of nuclear reactions that begins with an unstable nucleus and terminates with a stable one; also called a radioactive series. (Section 21.2)
Part per million (ppm)
Units used on NMR spectra to record chemical shift relative to the TMS standard.
parts per billion (ppb)
The concentration of a solution in grams of solute per 109 (billion) grams of solution; equals micrograms of solute per liter of solution for aqueous solutions. (Section 13.4)
An intermediate that has both a negative charge and an unpaired electron.
A law stating that the partial pressure of a solvent over a solution, Psolution, is given by the vapor pressure of the pure solvent, P° solvent, times the mole fraction of a solvent in the solution, Xsolvent: Psolution = XsolventP° solvent. (Section 13.5)
